pskey(1)                                     Qualcomm Atheros Open Powerline Toolkit                                    pskey(1)

NAME
       pskey - Print prescaler key

SYNOPSIS
       pskey [options] file [file] [...]  [&gt;stdout]

DESCRIPTION
       Read the prescaler section of a .pib file and print the SHA256 digest (key) on stdout.  The digest acts as a finger-print
       of the prescalers stored within and may be used to compare prescalers and detect changes.  Only the prescaler section  is
       read.  The rest of the PIB is ignored.

       This  program  is  part of the Qualcomm Atheros Powerline Toolkit.  See the AMP man page for an overview and installation
       instructions.

OPTIONS
       -q     Enable quiet mode.  This suppresses the filename after prescaler keys on output.

       -v     Verbose mode.  This option has no effect at present.  None.

ARGUMENTS
       file   The name of an Atheros Parameter Information Block (PIB) file.  This file is not  modified.   By  convention,  PIB
              files  have  a  .pib  extenstion  but  this program does not enforce that convention but invalid PIB files will be
              rejected on input.

DISCLAIMER
       PIB file structure and content is proprietary to Qualcomm Atheros, Ocala FL USA.  Consequently, public information is not
       available.  Qualcomm Atheros reserves the right to modify PIB file structure or content in future firmware releases with‐
       out any obligation to notify or compensate users of this program.

EXAMPLES
       This example prints the SHA256 digest for the prescaler section in file v3.3.4.pib.  The digest uniquely identifies  that
       particular prescaler set.  PIB files with the same prescaler digest contain the same prescaler set.

          # pskey v3.3.4.pib
          AF26B02BB5044BE70986A5C2F5705671213D63A7827928C240D131E940EF4FC4 v3.3.4.pib

       The next example is the same as before but does not print the input filename after the key.

          # pskey v3.3.4.pib -q
          AF26B02BB5044BE70986A5C2F5705671213D63A7827928C240D131E940EF4FC4

       The  next  example does the same for all .pib files in the current folder.  Observe that several files have the same fin‐
       gerprint and so contain identical prescaler sets.  Prescalers are designed to satisfy EMI requirements for various appli‐
       cations and world regions.  It is critical that the correct prescalers are used.

       The  next  example  does  the same as the previous one but sorts on the digest in order to group files by their prescaler
       sets.  This highlights the fact that we have four different prescaler sets in the group and two files are apparently dif‐
       ferent from the others.  The sort program is a Linux utility and may not be available on some systems.
